Drawing on over 30 years of experience in business English teaching and English for Specific Purposes (ESP), primarily in corporate training contexts, Evan Frendo set out to do two things during his webinar for MaWSIG on 5 June 2025: deconstruct English as a business lingua franca (BELF), and discuss its impact on the broader ELT industry, and offer some insights into the world of corporate language training materials and the opportunities it presents for materials writers. This is his summary of his presentation.
